The company who put in my 18 year old HVAC system did the spring inspection and this time the results suggested replacing this very expensive item. They gave me a quote but before I committed I called John C Flood. John C Flood sent out someone within a few hours to check out my situation, gave me a quote for the exact same equipment and service warranties for enough of a price difference for me to choose them. Then they had their folks come the very next day - the only day I could be home this week - and so far so good. Will test this when it gets hot this weekend but as for price and responsiveness, John C Flood gets an A+ from me!
